Also LSD may possibly be psychologically habit forming (depending on the individual) but is not physically habit forming.
Excellent point! When one looks at the impact of alcohol on the Aboriginal peoples of Canada and the Inuit. It makes one wonder? Remember Europeans would not have survived without access to wine because of tainted water issues! The Inuit and Canada's Aboriginal peoples had tons of good clean water but no need for alcohol!
Another good argument for Evolutionary Biology!
